Refreshing drink

Esther, my beautician taught me how to make this drink

Few stalk of lemon grass
Few stalk of pandan leave
Couple of red dates
Rock sugar to taste

When water boils, add the red dates and lemon grass, boil it for 5 min and then add the pandan leave and rock sugar and leave to boil for another 10 min.

Is refreshing and smell so nice while have it hot, so far had not try the cold version will update once i try it.
